Diesel against the other Audi Q5 versions
| Fuel | Pass rate | Tests |
|---|---|---|
| Diesel | 84.6% | 77,455 |
| Petrol | 87.9% | 18,835 |
| All Audi Q5 | 85.2% | 96,307 |
Why the fuel type changes the number
Diesels carry DPFs, EGR valves and stricter smoke limits, so emissions and exhaust faults account for failures petrol cars never see.
On the Audi Q5 specifically, petrol is the strongest at 87.9%, and this diesel version sits 0.6 points below the 85.2% model average.
What it means if you are buying one
There is little to choose between fuel types on this model, so decide on running costs and mileage rather than MOT record. Check the exact car, decode the VIN and check the mileage before you bid.
Mileage is part of the answer
The average diesel Audi Q5 had covered 82,493 miles at test, against 53,105 for the petrol. That is above average, the point where suspension bushes, drop links and exhaust corrosion start showing up as advisories before they become failures.
Fuel type and mileage are tangled together: diesels are usually bought by higher-mileage drivers, so some of any gap between fuels is the miles rather than the engine. The per-year figures on the Audi Q5 page separate age from fuel if you want to isolate one.
